Cracking/Hacking Windows Passwords (UPDATED: VISTA Too!!)





Introduction: Cracking/Hacking Windows Passwords (UPDATED: VISTA Too!!)

Instructional/Educational Purposes only.
Be nice kids.

First of all, and I have to say this because of some recent comments, this is not a virus, and will not delete any files from your computer. In fact, ophCrack, the software we're gonna use is a very popular password cracker. Google it or Wikipedia it if you don't believe me.

This works for WINDOWS ONLY

This will crack all windows passwords up to 14 digits on a computer.
You need physical access to the computer.
You don't need to be logged in (that's what this is for).
It will tell you all user names and passwords on the computer.

Step 1: Get the Resource

1. Go here:

2. Download the latest version of ophcrack live cd. To crack passwords on an XP computer select 'ophcrack XP LiveCD'. To crack passwords on a VISTA computer select 'ophcrack VISTA LiveCD'.

3.The software you download will be a CD image (.iso format). If you try opening this on a computer with a CD-Writer and CD-Writing Software (eg. Nero, Roxio, Record Now, or whatever you have) it will write that file to a CD.
So, make the CD

Step 2: Crack

1. Make sure the computer you intend to crack is off.

2. Turn on, and instantly pop in the CD you just created.

3. By this time, windows might have started loading. So, turn off computer by holding down power button and then turn on again. What you want to do is boot from the CD. This can be done in two ways:
a. Often pressing one of the function keys (depending on manufacturer) takes you into the BIOS setup (the first splash screen that pops up when you turn on your computer should tell you which one: often F2, F11 or F12.) There, you should look around until you find where you can change the boot order (this differs from company to company depending on your computer brand). Change the boot order, so the computer first boots from CD then from Hard Disk.
b. There is often another function key (again depending on manufacturer) which enters you into the boot selection menu where you can select where to boot from. Hit boot from CD.

4. Watch as the CD loads. It will load a temporary version of linux on to the ram, dump all user names in a box and start processing. This software can only crack passwords up to 14 digits. As it deciphers the passwords, it will decipher each password in two blocks of 7 characters each, and then show you the whole password as a combination of those two under the column labeled 'net password'.

5. Vola! In about 5-10 minutes you have all the user names and passwords on that computer.

Questions & Answers


I have completed everything, but it says that the password could not be found. Any suggestions as to what to do next?

I have a youtube channel dedicated to this kind of thing guys.

Here is my tutorial video using a similar process to above.

Well, I don't thinks cracking is a good idea, maybe you can recover Windows Vista password which can keep important data in your computer. I suggest you can use some Windows password recovery tool, there are many and you can search them on Google

good information for mine

Aftear launching the cd it comes to a screen that says "Welcome to open source SliTaz boot time: 12 s. Run: 'ophcrack dialog' to search again for tables. tux@slitaz:~$" I'm assuming it is waiting for a command. I have a vista hplaptop and made sure I downloaded the live cd for vista. Can anyone help

When I lost my Windows password, I try to find out one program from Google, finally use a tool to crack the Windows 7 login password, and it seems to supports all the Windows OS. I got this smart Windows key from CNET website: Windows password recovery

Actually to crack or hack Windows password, I use the SmartKey Windows Password Recovery, it is nice and wonderful! It works like a charm! You can Google it!

I also find some some useful videos about how to recover lost Windows password, and in my eyes, this video guide about how to recover lost Windows 7 password from Youtube is nice!

kernel panic – not syncing: Attemped to kill the idle task – this is what I got on the screen after selecting a mode with Ophcrack.. and downloaded the file twice and burned it twice.. got the same message..Eventually I purchase the paid software Password Recovery Bundle and it works! Thanks any way!
